Many of the devices featured on this website rely on the use of microphones.
They are used, for example, to covertly record
a conversation between two people,
bugging a room
or during (covert) surveillance operations.
In such
applications it is important that the microphone is not recognised as such,
which means it has to be nearly invisible or concealed in something else.

This part of the website shows some popular examples of microphones that can
be concealed effectively. Some of these devices are bare microphones that are
so small that they can easily be integrated with (or under) the operative's
clothing. Others are disguised as common objects.
